J., and Earl v Reinert Reber, Philadelphia, Pa. Application January 3, 1936, Serial No. 57,372 1 Claim. This invention relates to a blanket and has particular reference to a blanket suitable for use (Cl. 5--334) of lock stitches, as indicated at I2, are run par allel to the edges through the plies and tape and by the violently insane. Ordinary blankets cannot be used in insane 5 asylums since violent inmates readily destroy them. It is the object of the present invention to provide a strong blanket which, though it has the ñexibility and provides the warmth of an ordinary blanket, cannot be readily destroyed. lnteriorly of the tape to insure that the plies all along the edge are in close contact With each other, thus a?fordinga reinforced condition which O! makes it practically impossible to start a tear from the edge of the blanket. Besides the above stitching, the entire surface of the blanket is covered by crisscross lines of 10 This object is attained by so constructing the blanket that it offers no chance for a grip which would permit destructive tearing. It has been found that blankets so constructed stand up for lock stitches, as indicated at I4, which lines are 10 so run as to leave only relatively small areas which are not tacked down by the stitches. Pref erably the lines 0f Stitches are run at right an periods far exceeding the periods of life of ordil5 nary blankets. The improved construction will be apparent frcm the following description read in conjunction with the accompanying drawing, in which: Fig. l is a plan View showing a corner of the 20 improved blanket; and Fig. 2 is a perspective View partly in section and partly broken away te specifically show the constructional details which lead to the attainment of the desired object, 25 The blanket comprises an intermediate ply 2 of strong fabric, such as canvas 0r equivalents, for example, duck, etc, Prefer-amy this canvas or duck, though strong, is of such weight that the resulting blanket is readily flexible and, in 30 respect to handling or use, differs little from conventional blankets, The intermediate ply 2 is faced with plies 4 and e of conventional blanket material, for example, a heavy woolen material which will pro35 vide the necessary warmth and softness. This material alone is not particularly strong in its resistance to tearing or destruction. Tapes 8 of Woven type and of a comparatively heavy nature are inserted, as indicated in the 40 drawings, between one of the outer plies and the intermediate ply at the edges thereof and all four plies thus resulting are stitched together by non-raveling overseaining of a type which does not involve chain stitches and hence cannot be 4.5 destroyed readily. 'I'he type illustrated in Fig. 2, for example, comprising three threads, can only be destroyed with considerable diñ'iculty. Strong heavy thread is, of course, desirable, so that destruction by the teeth cannot be readily accomplished. In order to further reinforce the edges, lines gies, leal/ing Square 0r rectangular areas Whieh are preferably less than three inches on a side. 15 Desirably the areas are even smaller. As a re Snlt. Substantial Separation Of the Outer plies frein the intermediate Canvas ply is imDOsSible‘ and any grip on the outer fabric can only be at tained between the tips of the fingers, it being 20 impossible to grip a portion of the fabric within the hand. 'As a result, it is difficult to start a tear inwardly 0f the edges Destruction of the blanket described substan tially necessitates either the use of some me- 25 chanical means which, of course, should not be available, or destruction of the stitching. All of the stitching Sl'lOnld be 0f nOn-raVeling Charac ter and 0f Snell heaVY, Strengr thread that break ing, eVen by the use 0f the teetl'l, iS iInDOSSlble- 30 It will be clear that variations may be made in the specific embodiment of the invention With out departing from the advantageous features Which are herein claimed. What we claim and desire to proteet by Letters 35 Patent isi A blanket Comprising Outer plies 0f facing fab rie, an intermediate ply 0f Strong fabric Such as Canvas 01’ the like, the edges 0f said plies being ‘ Substantially aligned, tapes eXtending alOng Said 0 edges inside the outer plies, non-raveling over searning binding the edges 0f the plies and the tapes, closely arranged lines of lock stitches run ning along the edges and Penetrating the plies and tapes, and crisscross lines of lock stitches tp. through the plies thrOilghOut the entire blanket, the last lines being relatively closely arranged to prevent substantial spacing of the outer plies from the intermediate One.
